Not Updated For Current Season
The masteries shown here are not yet updated for the current season, the guide author needs to set up the new masteries. As such, they will be different than the masteries you see in-game.
I always start up buying Ruby and +Disintegrate.
And i go mid because i want the level advantage. Start last hitting minions with your Disintegrate and harras when your stun is ready.(Disintegrate+AA or Disintegrate+Incinerate+AA)Depends on how your mana is. Keep harrassing until lvl 6, and bring your stun up by last hitting minions with Disintegrate and Flash into your enemy and Tibbers - Incinerate - Disintegrate - AA + Ignite+AA if the targets dont fall.
Go back to base and buy Sorceres Shoes, Amplifying Tome and a Elixir of Fortitude.
On every recharge go initiate a kill either on your enemy in the mid or gank one of the sidelanes. Your skill order for a kill:
After 20 min i used to have these items: Sorceres Shoes, Mejai's, Ruby, Blasting Wand and maybe a Giant's Belt and a Elixir of Fortitude. I always or mostly choose health before anything else and i keep having an Elixir of Fortitude in my slot, if im about to die, it is happens lots of time that Fortitude elixir is my lifesaver.
At full build and lvl 18 you should have around 3700hp with Elixir of Fortitude.
Like Banshee's Veil usually prevent a Sion's Cryptic Gaze, Blitzcrank's Arm, Taric's Dazzle, Morganas immbolize or whatever.
You can swap:
Mejai's for Archangel
Banshee's Veil for Void Staff or Abyssal Scepter.
Yea you can swap whatever you want this is just how i play it.
Try keep your stun up all the time, if a enemy overextends Incinerate him and thats usually how teamfights start. And you can go in Tibbers+incinerate+... or whatever.
This is how i play her, looks the other guides for extra information.
